3 types of wine fermentation equipment
In the winemaking process, oak barrels, stainless steel fermentation equipment, and even some concrete tanks all play a very important role, so what are their advantages?

1 oak barrel


Before the appearance of stainless steel barrels, almost all wines were aged and stored in oak barrels, which have a long history as wine storage containers. 

The type, barrel type and roasting degree are the basic elements to distinguish different oak barrels. These different elements are also related to the impact of oak barrels on wine.

At present, the most commonly used and popular oak species selected in oak barrels are mainly Louvre Oak and Summer Oak from Europe and American White Oak, which is mainly produced in the United States.

One of the biggest benefits of oak barrels is that they can provide wine with unique oak barrel flavors, such as coffee, tobacco, vanilla and chocolate. 

These flavors brought by oak barrels are intertwined with the original fruity aroma and aging aroma of the grapes, which are favored and infatuated by most wine lovers.


In addition, because oak barrels are made of a certain number of oak barrels tied and baked, there are inevitably small gaps between the plates, which provides conditions for proper "micro-oxidation" of wine, which is beneficial to wine.

The natural maturation of the wine, the phenolic substances of the wine react with the aroma of oak barrels during the process of micro-oxidation, and the aroma of the final wine is more rich.


At present, most wineries that adhere to the traditional winemaking process still insist on using oak barrels in the winemaking process.

2 Stainless steel fermentation tank


The stainless steel fermentation vat is an inert container, cast from stainless steel, with good airtightness and strong corrosion resistance.
Why is the use of stainless steel fermentation tanks more and more popular? To a large extent, this is due to the durability and sustainability of stainless steel  fermenter.
The volume of stainless steel fermentation vessel is generally larger. In the case of brewing the same volume of wine, stainless steel fermentation tanks can save purchase costs than oak barrels. This is one of the reasons why some wineries choose stainless steel fermentation vessel to make wine.
At the same time, some winemakers believe that stainless steel fermentation containers can well retain the original personality and characteristic flavor of wine grapes, and the wine produced is more pure and natural.
The airtightness of the stainless steel fermentation tank with good sealing allows the winemaker to grasp the oxidation speed of the wine, and perform moderate oxidation according to the taste of the wine tasting, so that the quality of the wine can be monitored more accurately.

Furthermore, the smooth contact surface of the stainless steel fermenter is easy to clean, which can reduce the influence of the residual substances in the previous winemaking, which is one of the reasons for the sustainable use of the stainless steel fermentation jar.

3 Concrete tank


The prototype of the concrete tank can be traced back to ancient Greece and Roman times, when people mainly used amphora tanks to transport and store wine. Nowadays, the shapes and sizes of concrete tanks vary from standard oval to square, pyramid, and even egg-shaped.

Although the same inert container, the concrete tank is different from the stainless steel fermentation tank. The inner wall of the concrete tank has a certain degree of air permeability. 

The wine can have limited contact with oxygen, so that the texture is softened. At the same time, the concrete tank does not give wine anything like oak barrels. 

Other flavors allow the wine to retain its freshness and purity. The finished wine is often dominated by fruit, with a bright style and smooth taste, often with mineral flavors.


Therefore, when winemakers do not want the obvious oak flavor in the wine and want the wine to be in contact with oxygen in an appropriate amount, they often choose to age the wine in concrete tanks.

For the comparison of the three, there is no dispute between high quality and cheap, nor between orthodox and wild. The choice of oak barrels, stainless steel fermentation tanks, or concrete fermentation tanks in the winemaking process is all based on the winery’s reasons. The choice for considering the expected quality of the wine.

Paragon can provide various types of stainless steel wine fermentation tanks, if special requirements, custom fermentation equipment can be accepted.
